I am getting magnetic interference on the screen when pushed back against the wall next to the pinball table.

Can you describe the interference -- is it a shimmering (moving) distortion of an otherwise OK display or is it a discolouration in certain areas of the CRT (perhaps the corners)? If it's moving, are you seeing a 'band of movement' progress up or down the screen or is it a 'jaggedy' left-right movement affecting the whole display? Or is it something else entirely?

A picture, as they say.....
